I've been working on this too, and I don't really understand it. I've rewritten this post a few times now, but every time I test one of my theories I easily find a counterexample. It appears that the two btTransform() arguments to btSliderConstraint() define the axis of translation, and have some ef...

Long story short: I was on bullet 2.66b, which doesn't have m_appliedImpulse. bullet 2.68 does, and now that I've upgraded my life is much simpler. Thanks for your help!

Erwin: I considered that, but couldn't figure out how to get the collision force from the contact points (the collision normal would be the average of the contact normals, I guess). Is there some way to infer that from btManifoldPoint::getDistance()?

I'm trying to register a callback that runs whenever two objects collide, but I can't figure out how. I don't want to prevent collision, or interfere with collision response in any way, just run some arbitrary code on each pair of colliding objects with their collision information. I feel certain th...
